VMware and Xen Management with BixData

Post date: November 16, 2006, 20:11 Category: System Views: 3420 Comments
Tutorial quote: BixData is a system, application, and network monitoring tool which allows you to easily monitor nearly every aspect of your servers. The newly released version 2.6 is the only application that has the ability to control both Xen and VMware virtual machines. You can control both VM Hosts (the computer that's running the VM software) and VM Guests (the virtual machines running on the hosts).

Xen: How to Convert An Image-Based Guest To An LVM-Based Guest

Post date: April 19, 2009, 10:04 Category: Miscellaneous Views: 3160 Comments
Tutorial quote: This short article explains how you can move/convert a Xen guest that uses disk images to LVM volumes. Virtual machines that use disk images are very slow and heavy on disk IO, therefore it is often better to use LVM. Also, LVM-based guests are easier to back up (using LVM snapshots).

Optimizing Desktop Performance, Part I

Post date: May 16, 2005, 23:05 Category: Optimizing Views: 3715 Comments
Tutorial quote: If you have complained about the speed of OpenOffice.org or Firefox or about the amount of time Linux takes to boot up, this set of optimizations should change your perception. Linux can boot up quickly, the word processor can spring open and the browser can fly. So, let's make these adjustments so your computer can fly.

Dual-Booting Windows XP/Vista And Ubuntu 7.04

Post date: July 21, 2007, 00:07 Category: Desktop Views: 4288 Comments
Tutorial quote: In this tutorial I will teach you how to dual-boot between Windows XP/Vista and Ubuntu. This tutorial will be split up into two parts: Part one for people who have no operating system installed. Part two for people who have Windows XP/Vista installed and do not want to re-install Windows.

Connecting to a Wireless LAN with Linux, Part 2

Post date: April 13, 2005, 19:04 Category: Hardware Views: 3684 Comments
Tutorial quote: In Part 1 we reviewed hardware options, which wireless utilities should be present, how to use Windows drivers, and how to be open to connect to any available wireless access point. Today we'll cover configurations on Red Hat- and Debian-type systems, basic security, and hardware discovery.

Wireless connectivity can be rather overly friendly, allowing connections from anyone. This howto assumes you have a wireless access point on a LAN, which can be all wireless or mixed wired and wireless. You don't want it wide open to just any random person with a desire to snoop on your network or "borrow" your bandwidth, but you want some access controls and security. Your access point should have a unique SSID (service set identifier), WEP (wireless equivalent privacy) or WPA/WPA2 (Wi-fi protected access) set up and working, and either a DHCP server or a pool of assigned IP addresses for clients.

KVM & OpenVZ Virtualization And Cloud Computing With Proxmox VE

Post date: February 17, 2009, 12:02 Category: Installing Views: 19069 Comments
Tutorial quote: Proxmox VE (virtual environment) is a distribution based on Debian Etch (x86_64); it provides an OpenSource virtualization platform for running virtual machines (OpenVZ and KVM) and comes with a powerful, web-based control panel (it includes a web-based graphical console that you can use to connect to the virtual machines). With Proxmox VE, you can even create a cluster of virtualization hosts and create/control virtual machines on remote hosts from the control panel. Proxmox VE also supports live migration of virtual machines from one host to the other. This guide shows how you can use Proxmox VE to control KVM and OpenVZ virtual machines and how to create a small computing cloud with it.

Optimizing Desktop Performance, Part II

Post date: May 24, 2005, 18:05 Category: Optimizing Views: 3398 Comments
Tutorial quote: As we discussed in last week's article, for most of its existence, people have distributed Linux as a workstation or a server rather than as a desktop. The default workstation that evolved has existed mostly for use by developers. So, when you install a Linux distribution with a graphical interface, it generally looks like what a developer might want. In addition, it performs similar to how many UNIX workstations work, which can seem slow.

In this article, we continue to look at the Linux desktop in a different light. Here, we think of it as a computer system with a fast interface that we can optimize for the knowledge worker and consumer.

Load-Balanced High-Availability Web Cluster With 2 Xen Servers On Ubuntu 8.04

Post date: October 12, 2008, 12:10 Category: Installing Views: 2998 Comments
Tutorial quote: In this howto we will build a load-balanced and high-availability web cluster on 2 real servers with Xen, hearbeat and ldirectord. The cluster will do http, mail, DNS, MySQL database and will be completely monitored. This is currently used on a production server with a couple of websites. The goal of this tutorial is to achieve load balancing & high availability with as few real servers as possible and of course, with open-source software. More servers means more hardware & hosting cost.

A web server in a shell script

Post date: March 14, 2006, 08:03 Category: Programming Views: 16516 Comments
Tutorial quote: Suppose you want to experiment a little with web pages and CGI's, but you don't want the hassle of installing the full Apache package. This quick and dirty shell script could just be what you need.

Put simply, a web server is an application that sends local text files over the network to the clients that request them. If you let another program (for example inetd) deal with the network part, the web server could be reduced to a mere cat "$filename" to stdout. Of course, the difficult part would be to extract that filename out of the HTTP request string: nothing that a Bash script cannot easily do!
